JOHN DAY, OF BROOKLYN, NEW YORK.

CURTAIN-PIN.

SPECIFICATION forming part of Letters Patent No. 275,160, dated. April 3, 1883.

(No model.)

T 0 all whom it may concern Be it known that-l, JOHN DAY, of Brooklyn, in thecountyof Kings and State of New York, have invented an Improvement in Curtain- Pins, of which the following is a specification.

Curtain-pins have been made with an ornamental head and screw-shank. My improvement is for the purpose of strengthening the shank of the curtain-pin without increasing the cost.

In the drawings, Figure 1 is a section longitudinally of the curtain-pin. Fig. 2 is a cross-section at w 00, and Fig. 3 is a plan of the back plate.

Ornamental heads for picture nails and ourtain-loops have been made with a head of glass, similar to the ornament a, and with a rim, b, around the same, by which the ornamental surface is attached to the back plate, 0. This feature in itselfI'do not therefore claim. I prefer to employ a back plate, 0, of heavy sheet-iron, and either enamel the back surface or else introduce a plate, 0, of thin japanned iron or other smooth sheet metal.

The stemfof the curtain-pin is made with a screw, i, at one end, and the other end is reduced to tit a square or polygonal hole in the back plate, 0, and the end of the stem is riveted up. In stems for curtain-pins it has been usual to make a flange upon the stem itself,

so as-to form a base to screw against the woodwork of the window-frame. This renders the stem expensive, and it is easily bent.

I make use of the wooden shank 71, that is hollow for the screw-stem to pass through and the surface is turned with ornamental moldings and coves. I also prefer to make use of a feather, 1, upon the stem, entering a slot in the shank, or to use some other device that connects the shank and screw-stem, so that they are turned with and by the shank in screwing the curtain-pin into the wind0w-casing. This shank serves to stiffen the stem, and, being clamped between the back plate of the head and the window-casing, it forms a Very firm and strong stem for the curtain-pin, and improves the appearance of the article.

I claim as my inventionlhe improved curtain-pin comprehending the ornamental head a, the metal back plate, 0, the clamping-rim b, the screw-stem f, riveted at one end to the metal back-plate, and the hollow ornamental shank surrounding the screw-stem, substantially as set forth.

Signed by me this 17th day of November, A. D. 1882.

JOHN DAY.
